Hello All,

Need some help on the right tires size. Unfortunately don't want to screw up since I can't return tires once they are mounted. I have the following wheels spec below. They will be on an 2001 Lexus IS300. I'm looking for a tuck setup up
(when airing down) and will be on Air Suspension. Not looking for a big stretch but can live with a minimal stretch. Thanks to all in advance.

Wheel Setup:
-Front 18x9 +45
-Rear 18x9.5 +40
